"Why would he do that? He had so much to live for!"
"Did you know him?"
"Well... no."
"Then how do you know what he had to live for?"
"He had a wife and kids! Grandchildren! He had more friends than anyone I've ever known. He was an innovator. Everywhere he went he was part of something above ground. He made everything around him better. I don't understand."
"Well of course you don't, you didn't know him."
"Is there something you know that would explain this?"
"What can I say to you that will make you stop this quest? Please... he was my very good friend. He introduced me to my wife and saved me from a wasted life of drugs and booze. I owe the man everything I have."
"Then Wh-"
"Please, just respect my friend. He didn't want anyone to ask questions. It said so in his note. Just leave it be. He deserves that much."

And with that, the door was closed. I had run out of places to go. The map I had created, provided by my own piqued interest and undying curiosity, had lead me down a one way street with no place to turn around. I started thinking about her. If she was worried about me. I wondered if my friends noticed I hadn't been around the last week. No one has called. Then again, my phone has been off. I don't know why I was doing this. I... I had to know why he did this to himself.

The door opened.

"Why do you have to know?"
"I feel like... I feel like this is something that is very important."
"Important enough to leave everything behind and go on this crazy quest knowing you will likely piss off whoever you find that knew him?"
"Yes. I can't explain... You ever feel like you knew someone better than anyone else before you even met them?"
"Can't say that I have."
"Well, I would've agreed with you a week ago."
"I can't tell you why he did it. I can only tell you what I knew of him... that he was a great man."
"I'd like to hear the stories."
"Then why don't you come in."
